hi just finished putting new motors, torpedo 800's in my tug had it running off one 12 volt batt with two 20amp viper speed controllers removed one esc red wire so each prop was individually controlled as no rudder, tank turn all was well in test so today tidyed the wires and fixed them in place and tested it again one of my esc kept blowing fuses and smelt of burning this is the one that powers the receiver took it out of the boat tested it on a battery and puff of smoke phoned howes were i bought them they said send it back and we will look at it never had any issues with vipers so hoping its just a dodgy esc will let you know how i get on and but some picks of my boats up cheers Mark
